To all whoqn it may comer n:

- Be it known that I,

GEORGE \V. STANLEY,

' aciti zen of the United'States, residing atj Logansp'ort,'in the county of Cass and State of.Indiana,;have' invented'a new and use- .ful Improvement in Differential Hubs, of

object being to provide a device by means of which the hub can rotate -axle or shaft.

faster than the .Another object of my invention is to pro videfa device which is especially adapted to be'u'sed on automobiles, the object being to provide a device by means of which the outside wheel of an automobile when turning a corner will be allowed to revolve faster than the inside wheel so as to prevent skidding.

A further object of my invention is to' 1 provide a ball and socket locking device which will take the place of the differential gear nowin use on automobiles and other vehicles, the 'ball and socket locking device being soconstructed that it will allow the vehicle to be run forwardly and backwardly.

A still further object of the invention is..

to provide apair of locking balls so mounted that when the wheel is being driven'forwardlyf both of the balls will be in a locked position and'when reversed 'oneof the balls will bejthrown out of engagement. v p Another object of the invention is to provide a ball and socket locking device in i which the balls are so mounted that when the hub of the wheel is rotated faster than the collar carrying the balls, the balls will be picked up by anchor shaped points formed the inside wheel and as soon; as the machine is driven straight locked. a

A further object of the invention is to again, the ballswill be "provide a ball and socket locking device whichis exceedingly simple in construction and one which is composed of a'very few parts which are so arranged that. they are not' likely to get out of order in usethereby wheel backwardly.

-Vith these various objects in View, my

overcoming the difiiculties now existing with diflerential gears used on automobiles.

A still. further object of my invention is one of the balls used for driving the wheel forwardly will pass diagonallythrough the collar and-assume a position todrive the invention consists in-the novel features of construction, combination and arrangement of parts hereinafter fully described, pointed to so construct the ball carrying collar that out in the claims and. shown in the accompanying drawings, in which Figure 1 is a vertical section through a hub showing the balls in a locked position.- Fig. 2 is a section taken on the line 2-2 of Fig. 1. Fig. 3 is a similar section'showing 'the ball picked upby the anchorshaped point. allowing the hub to rotate freely. Fig.

the other side to that of Fig. 2.

Fig. 6 is a section through the fluted box. Fig. 7 is a section taken from- In carrying out my improved invention,-

I employ a collar A which is adapted to be' secured to the rear axle Bofan automobile v by pins Av and a key A which securely' looks the collar rigidlythereon so that when the axle isrotated thecollar will be also rotated. The collar is provided with oblique grooves C and D forming. shoulders C, D.

' and anchor shaped points 6 ,13 for a purpose hereinafter fully described. An oblique groove or recess E is formed in the collar on the side with-the recess or groove D and is also providedwith a shoulderE' and an I anchor shaped point E the recess being connected to therecess G'by a diagonal bore F for a purpose hereinafter fully described; Mounted on the axle B is a hub-G of any suitable construction having a fluted box H 'provided'with a flanged end H and providedwith an internally threaded portion H- in which is'adapted to work an externally threaded nut or sleeve 1.

Mounted in the groove or recess C' is a.

locking ball J which is adapted to'fit within one ofthe flutes of the box when in a normal posit-lone ainist the shoulder C so that recess D is an idle ball I; which is also adapted to fit within a flute of the box when in a normal position so that when the wheel is being driven forwardly the hub will' be locked to the collar by the balls, the grooves O and D being arranged in exactly the same position in'the collar with respect to each other so that when the axle is being rotated in the direction to drive thewheel forward, the'balls J and K will be in a locked position and when the axle is reversed so as to turn the wheel backwardly, the ball J will pass through the diagonal bore F into the oblique. groove or recess E and drop into one of the flutes of the box and be engaged by the shoulder E which looks it in a firm position so that the wheel can be driven backwardly without any danger of it-slipping. hen the axle is again driven forwardly the ball J will be picked up by the anchor shaped point E and carried through the diagonal bore into the recess G where it will drop into the flute of the box and be engagedby the shoulder C. The ball K will also drop in the same flute so as to form a double lock and when the wheel is being driven backwardly the ball K will pass into the bottom of the groove or recess and be held in thatfposition until the wheel is again driven forwardly.

Assumingthat the balls are in a locked position as clearly shown in Figs. 1 and 2 which shows the wheelbein driven forwardly and when a corner 15 turned the outside. wheel will rotate faster than the axle is being drivenwhich forces the balls J and K up 'on the anchor shapedpoints v C D thereby allowing'the wheel to rotate independently of the collar, the balls being held out of engagement with the hub, and

owing to the movementof the parts these balls are held in a neutralfor inoperative position; that is they are prevented by centrifugal or other forces from passing through the collar to the opposite side. When all of the parts have assumed their normal conditions the balls will drop into" their proper places and the wheel will. be locked with. reference to the axle. I

While I have shown and described my improved ball and socket locking device especially adapted to be used on a hub for ai1 tomobiles, it is of course understood that it can be used in connection with any driving.

means without changing the construction.

From the foregoing. deseriptiomit will be seen that I have provideda diil'erential hub which is operated by a-ball'and socket locking device so constructed that thehub will be locked in a rigid position on the axle when going straight and will be released when a corner is being turned, so as to allow the outside wheel to rotate faster than the inside wheel.

What I claim is 1. The combination with. a power axle,

of a collar fixed upon said axle provided with oblique recesses or grooves forming shoulders and anchor shaped points, said collar being provided with an oblique recess or groove connected to one of the first mentioned recesses or grooves by a diagonal 'borea ball mounted'in said recess or groove, an idler mounted in the other recess or groove and a hub provided with a fluted box mounted on saidcollar adapted to be locked inposition to be driven forwardly or backwardly by the live ball.

2. In a device ofthe kind described, the combination with a power axle, of a collar fixed on said axle, obli ue grooves or recesses being formed in sai collar and a,

diagonal bore connecting said grooves or recesses, balls mounted in said recesses, one of said balls being adapted to pass through the bore, a hub mounted on the collar and provided with .a fluted box adapted to be locked to said collar by said balls when in one position, and to be driven forwardly,

and in reverse positionto be driven backwardly.

3. In a, device of the kind described, the combination with a poweraxle, of a collar secured .onsaid axle; oblique recesses or grooves formed on opposite faces of said col-lar connected together by a diagonal bore, a fluted box carried by a hub mounted onsaid collar and a ball loosely mounted in said recesses for driving said hub in one direction when in one recess and for driving the hub in a reverse direction in the other recess.

4. Ina combinaticn with a power axle, of a collar fixed on said axle provided with oblique grooves or recesses forming shoulders and anchor shaped points, said recesses being connected together by a' diagonal bore, a fluted box loosely mounted on said.collar' and a ball loosely mounted in said recesses for driving said fluted box in a forward or backward direction.
